2015 Map of Needle Reservoir

About this map

Antelope Knoll stands as a prominent high point in this high-desert region of Sweetwater County, overlooking a landscape defined by seasonal drainage patterns and ranching water management. The terrain is carved by the long, winding Tin Can Draw and Cattail Draw, which channel intermittent runoff through the arid basins. These natural features are supplemented by human-made infrastructure designed for livestock and land management, including the Big Hollow Reservoir, Badlands Reservoir, and the namesake Needle Reservoir. The 2015 survey reveals the intersection of several public land survey townships, including t16n r111w and t15n r111w, illustrating how the western grid is imposed over the irregular topography of the Wyoming plains.
